They have a check ball in the bleed passage. As you suction or pump fluid, the ball uncovers the passage port. You loosen the hex and that allows fluid to flow out but when you stop, the ball blocks air from being drawn in.
No pumping or second person needed. When fluid is clear with no bubbles, lock the hex.
To prevent air bubbles at the hose connection, coat the nipple with antiseize and use a zip tie if needed.
